Question

If the sum of first 'm' terms of an AP is 'n' then the terms is m then show that the sum of it's first (m+n) terms is -(m+n)

Answer 1

If the sum of m terms of an AP is n and the sum of n terms is M then the sum of m'n terms is

If the sum of m terms of an A.P. is the same as the sum of its n terms, show that the sum of its (m+n) terms is zero. Let a be the first term and d be the common difference of the given A.P. Then, Sm=Sn

Answer 2

If the sum of m terms of an AP is n and the sum of n terms is M then the sum of m'n terms is

If the sum of m terms of an A.P. is the same as the sum of its n terms, show that the sum of its (m+n) terms is zero. Let a be the first term and d be the common difference of the given A.P. Then, Sm=Sn
